参数：

类型参数名称
intargc
const char **argv
2352  如果argc恒等于0则The user may not realize that ps/bta with no parameters does not print idle* or sleeping system daemon processes, so tell them how many were suppressed.
2354  kdb_printf("%-*s Pid Parent [*] cpu State %-*s Command\n", (int)(2 * *的长度) + 2, "Task Addr", (int)(2 * *的长度) + 2, "Thread")
2357  mask等于kdb_task_state_string(argc ? argv[1] : NULL)
2359  遍历在线CPU(cpu)
2360  如果KDB_FLAG(CMD_INTERRUPT)则返回:0
2362  p等于kdb_curr_task(cpu)
2363  如果kdb_task_state(p, mask)则kdb_ps - This function implements the 'ps' command which shows a* list of the active processes.* ps [DRSTCZEUIMA] All processes, optionally filtered by state
2366  kdb_printf("\n")
2368  Simplify coexistence with NPTL (g, p)
2369  如果KDB_FLAG(CMD_INTERRUPT)则返回:0
2371  如果kdb_task_state(p, mask)则kdb_ps - This function implements the 'ps' command which shows a* list of the active processes.* ps [DRSTCZEUIMA] All processes, optionally filtered by state
2373  kdb_while_each_thread(g, p)
2375  返回:0
